In civil engineering and mining projects, blasting is frequently used to break rock masses. Often, there are sensitive structures or facilities located near the blasting site that may be affected by excessive particle velocity. Measuring blast vibrations with the aim of minimizing Peak Particle Velocity (PPV) is therefore one of the key responsibilities of professionals in mining and construction projects. Geopersian has, over the past years, designed and developed integrated systems consisting of sensors, recorders, and specialized software for blast monitoring in numerous civil and mining projects across the country. In 2025, our knowledge-based company was awarded the tender to supply four blast monitoring devices for the Darreh-Aloo Copper Mine in Rafsanjan. Considering that the technical team of Rafsanjan Copper Mines is among the most professional client teams in the country, we strived to enhance our previous devices and deliver equipment that meets the latest international standards. In this process, we benchmarked against the world’s leading blast monitoring technologies to ensure the highest quality and reliability.

Offshore oil platforms are exposed to numerous destructive factors. Continuous exposure to sea waves, corrosion, fatigue, collisions, and machinery vibrations progressively deteriorates these structures. Until now, visual inspection methods had been employed to assess damage levels; however, limited accuracy and difficult accessibility have caused significant uncertainty in devising reinforcement strategies for these structures. Following the emergence of Fourth Industrial Revolution technologies, the Iranian Offshore Oil Company decided to revolutionize the monitoring of these structures through vibration sensors and artificial intelligence processing methods. This undertaking was entrusted to the knowledge-based company, Geopersian

The production and calibration of the equipment were carried out by Geopersian.

The massive support structure of the Rafsanjan Copper conveyor sustains a belt that transports between four and six thousand tons of ore per hour to processing plants, and any required repairs or overhauls would effectively halt mine production. Early damage detection and the implementation of preventive maintenance operations without disrupting operations are key objectives of the National Copper Company in deploying this system. Given the expanded range of threats—from earthquakes and subsidence to security risks, war, and explosions—this system plays a critical role in decision-making for emergency evacuation, enhancing resilience, reducing recovery time, and is considered an essential component of passive defense.

The 2018 Sarpol-e Zahab earthquake triggered widespread trauma among the Iranian population and caused significant financial losses and casualties.

The Northern Karaj Bypass, running along Tehran’s Hemmat Highway and passing the Azimieh Bridge, is planned to directly connect Tehran to the Karaj-Qazvin Freeway beyond Kordan, alleviating the daily traffic bottleneck in Fardis, Karaj. Due to the construction of entry and exit ramps, it was necessary to remove rocky outcrops near electrical facilities and bridges along the route using controlled blasting to accelerate the project. Blasts had to be carefully managed, with explosive quantities and maximum particle velocities adjusted to avoid damage to existing structures. The measurement of blasts and the development of operational formulas were carried out by Geopersian.

The Tehran-North Freeway is one of the country’s major transportation routes, passing through the mountainous Central Alborz region. Numerous bridges and tunnels in the area were constructed in a high seismic activity zone, and traffic loads, combined with geological and tectonic changes, have caused various types of structural damage. In 2021, it was decided to equip the largest bridge along this route with vibration monitoring systems. This project was carried out by Payab Zamzam Company on behalf of the Tehran-North Freeway Company, with consulting from Rahyab Mellal Company, all under the supervision of the Mostazafan Foundation.
